keydown事件，写这种代码

If e.control = True AndAlso e.keycode = keys.v Then
    '执行代码
    Dim str As String = ClipBoard.GetText
    Dim nstr As String = ""
    Dim tempstr As String = ""
    Dim flag As Boolean = False
    For i As Integer = 0 To str.length - 1
        If str(i) = """" Then
            If i = 0 OrElse str(i-1) = chr(9) OrElse str(i-1) = chr(10) Then '开始
                flag = True
            ElseIf i = str.length-1 OrElse str(i+1) = chr(9) OrElse str(i+1) = chr(13) Then '结束
                tempstr = tempstr.Replace(chr(13), "")
                nstr &= tempstr
                tempstr = ""
                flag = False
            End If
        End If
        If flag = True Then
            tempstr &= str(i)
        Else
            nstr &= str(i)
        End If
    Next
    ClipBoard.SetText(nstr)
End If

1、excel文件发上来测试；

2、贴出你keydown的事件代码。

改成这样

If e.control = True AndAlso e.keycode = keys.v Then
    '执行代码
    Dim str As String = ClipBoard.GetText
    Dim nstr As String = ""
    Dim tempstr As String = ""
    Dim flag As Boolean = False
    For i As Integer = 0 To str.length - 1
        If str(i) = """" Then
            If i = 0 OrElse str(i-1) = chr(9) OrElse str(i-1) = chr(10) Then '开始
                flag = True
            End If
            If i = str.length-1 OrElse str(i+1) = chr(9) OrElse str(i+1) = chr(10) OrElse str(i+1) = chr(13) Then '结束
                tempstr = tempstr.Replace(chr(13), "")
                nstr &= tempstr
                tempstr = ""
                flag = False
            End If
        End If
       
        If flag = True Then
            tempstr &= str(i)
        Else
            nstr &= str(i)
        End If
    Next
    msgbox(nstr)
    ClipBoard.SetText(nstr)
End If
